Keep in mind that 'information propagation' is pretty fundamental: we can use it to define light cones (if A can propagate information to B, then A/B are in each others past/future light cones). We can use light cones to define time (past/future) and space (neither). That's a pretty standard approach to relativity (I can't remember whether I covered it as an undergraduate, but I certainly encoutered it around that time). (Shannon) information theory is also closely related to probability, and quantum theory is a form of probability theory (e.g. https://arxiv.org/abs/quant-ph/0101012 https://arxiv.org/abs/quant-ph/0101012 ). Hence it's not entirely out-there to think that an informational/computational approach like Wolfram's might bear fruit. In fact, I was hoping that someone smart(er than me) would investigate such connections a bit deeper; if only to rule them out! Note that "causal set theory" seems to be going that direction too (although I'm not overly familiar with it) https://en.wikipedia.org/wiki/Causal_sets https://en.wikipedia.org/wiki/Causal_sets I also find it promising that ideas from quantum computing (qbits, circuits, teleportation, protocols, etc.) have gone from a quirky engineering footnote (in the 90s), to become a core part of how many physicists now think about the world.
